SPINNING, TWISTING, AND LIKE APPARATUS.

Specification of Letters Patent.

Patented June 30, 1908.

Application filed June 27, 1905. Serial No. 267,187.

To all whom it may concern:

Be it known that I, HENRI DOLL, a citizen of the Switzerland Confederation, residing at Paris, in the Department of the Seine and Republic of France, have invented certain new and useful Improvements in Spinning, Twisting, and Like Apparatus, of which the following is a full, clear, and exact description.

These improvements relate to apparatus of the'type described in the specification to my Letters Patent filed 10th August 1904 Patent No. 815,07 5 and their objects are to improve the construction of the revolving ring under which the thread or yarn passes and to improve the method and means by which such ring is attached to its spindle so that no objectionable vibrations are set up even at high speeds. The latter object is achieved by securing the ring to its spindle by a joint which will permit rocking in any direction but which will compel the rin to rotate with the 0 v e o splndle. A ring so mounted is capable of as suming and maintaining a position of equi librium during its rotation without deforming the spindle to which it is attached.

It is preferred to employ the form of joint known as the Cardan joint, but any other jointing device which will permit or compel the required movements may be used.

The accompanying drawings illustrate the improved devices and will now be referred to.

Figures 1 and 2 show the jointing device by which the ring is attached to its spindle in vertical cross sections taken at right angles to each other and respectively along the lines rw and y-y of Fig. 3. Fig. 3 represents the jointing device in horizontal section taken along the line zz of Fig. 1.

(m) is the ring under which the thread or yarn passes, and it is formed upon or attached to a cylindrical or bell shaped part (a) which is secured to the upper end of the spindle by the means hereinafter described. This ring may be smooth on its under surface as illustrated in the drawings.

(a) is the spindle, and (b) is a piece partly spherical on its outer surface which is rigidly secured by friction or by other means to the upper end of the spindle.

(cl) is a ring secured to or integral with the bell shaped part (n).

(c) is an intermediary ring placed loosely between the part (1 and the ring ((1) and having its outer surface rounded so that rocking motion is freely permitted.

(0) is the upper end of the bell shaped part (a).

(f f) are two loose balls or equivalents situated at the opposite ends of a diameter of the ring (0), and partly seated within such ring (0) and partly within the part (b). (g g) are two similar balls situated at opposite ends of a diameter at right angles to the former diameter and partly seated within the ring (0) and partly within the ring ((1).

FILATURES DE BOURKE These balls are so proportioned and mounted in their seats that rocking movement in any direction of the bell shaped part and the ring attached to it is freely permitted upon the spindle.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

In a spinning apparatus of the class described, a rotary spindle, a bell-shaped part surrounding said spindle and hinged thereto to permit movement laterally in any direction with respect to the spindle, but constraining the bell-shaped part to rotate with the spindle.

In witness whereof, I subscribe my signature, in the presence of two witnesses.

HENRI DOLL.
